Detecting Edge Legacy browser, not Edge Chromium

ArcGIS is depreciating use of IE11 and Legacy Edge browsers with current and future versions of their JavaScript API.

I'd like to know how to target legacy version of edge and alert users things may not work properly. Using:

navigator.userAgent.indexOf("Edge/") > -1 || navigator.userAgent.indexOf("Edg/") > -1;

does not work since Chromium Edge is still edge in the user agent. Is there anything else I could use that would allow me to differentiate between the two?

Solution

  • It's Edg in Edge Chromium user agent and Edge in Edge Legacy user agent. So you only need to use Edge to detect Edge Legacy:

    navigator.userAgent.indexOf("Edge/") > -1
